ALBANY — Lee Kindlon is leading Albany County District Attorney David Soares by more than $15,000 — nearly a 3-to-1 advantage — as the two Democrats head into a September primary, the latest campaign filings show.

Kindlon, an Albany-based defense attorney, holds a war chest of $23,399, compared with Soares' $8,210, according to campaign records filed with the state Board of Elections.

It is the third consecutive filing period that has ended with Kindlon leading the two-term incumbent in campaign dollars. The GOP candidate, David Price, raised less than $1,000 and did not submit any figures to the Board of Elections, Albany County Republican Chairman Don Clarey said via Twitter.

Over the course of the campaign, Kindlon's donations included $15,000 from his father, high-profile lawyer Terence L. Kindlon; a $5,000 loan from his in-laws, Nick and Laurel Bodnar of Kennerdell, Pa.; and $2,500 from himself. He received contributions from at least two dozen lawyers or law firms from New York to Arizona. Soares' contributions included a combined $25,000 from billionaire Manhattan-based financier George Soros and his son, Alexander Soros, who donated $12,500 each.

Kindlon, of Delmar, told the Times Union of his initial plans to challenge Soares in March 2011. He officially announced his candidacy in December. Since mid-January, when the last financial filings were released, Kindlon raised $57,989, Soares $38,719.

Kindlon has outspent Soares since that point, $97,089 to $74,676.

"We've outraised our opponent now for the third straight finance period. We are comfortable that we will have the resources we need to ensure that Lee is victorious on election day," Kindlon's campaign manager, Eddie Ayala, said Tuesday.

Brad Maione, spokesman for Soares' re-election campaign, said he was "very confident that we will be very competitive." He noted that Soares did not officially announce his run for a third term until June 4.

"It is obvious that he has marshaled forces with the defense bar, which is problematic because those are the people that David's policies, in terms of DWI and one standard of justice, made them concerned about how David approaches the office," the spokesman said, noting that Soares toughened his office's DWI policy in 2008.

He also took at jab at Kindlon's support, adding, "He's certainly tapped his family for significant amounts of money."

Ayala, in turn, said: "After eight years of the incumbent DA, to report as little financial support as he did, shows that he has lost Democratic voters in Albany County."
